SNOW-SCRAPER.

I Specification of Letters Patent.

Patented Oct. 20,1914.

` Application filed February 28, 1914. Serial No. 821,800.

to which it appertains to make and use thel same.

This invention relates to Scrapers, and

while especially adapted and intended fork scrapers to be employed forremoving snow from ice for harvesting, it is not limited to such use orsuch purpose and is applicable to any form of scraper where it isdesired to scrape and remove material surface. y

An object of the present invention is to provide a frame to which draftmay be applied with wings pivoted thereto meeting at the rear in a V andwith means for re leasing the wingsto permit them to assumesubstantially parallel positions to discharge the load and also to serveas runners for ytransportation of the scraper.

With these and other objects in view the invention comprises certainnovel constructions, combinations and` arrangement of parts as willl behereinafter more fully described and claimed.

In the drawings: Figure 1 is a top plan view of the improved scraperwith the wings closed. Fig. 2 is a view of the scraper in end elevationas indicated by arrow 2 at Fig. 1. Fig. 3 is atop plan view of thescraper showing the wings open in parallel position for discharging theload and transportation. Fig. l isa sectional view taken longitudinallycentrally through the device as indicated by line 1 -J1 of Fig. 3.

Like characters of reference designate corresponding parts throughoutthe several views. l

The improved scraper which forms the subject matter of this applicationcomprises a frame which may be of any approved or desired form orconstruction, here shown as comprising a cross beam 10 substantiallystraight, and a curved beam 11 connected with the beam 10 at itsopposite ends and spaced centrally therefrom by parallel-bars 12. yThesebeams are preferably of angle iron as shown, and their lower edges standin a single horizontal plane.

from a given Apole 13,701' any approved form'of attaching draftjto theframe is provided so that the frame-,may be moved over the surface whichitis Adesired to clean. V

Atits opposite ends theframe 'composed of the members '10 and 11 isprovided with downwardly extending pintles 14: upon which the front endsy"of'wings 15 are pivoted in any approved manner as by employing abracket-p16 secured to. the exterior of each of said wingsand havingeyes throughwhich the pintles 14 extend. Each wing stands uprightbeneath the framework andv is lirmly supported on the pivot at its frontend, its' upper edge passing under and in contact with the beams 10 and1l above, whatever the position of the wing, and by this1 means ltheframework is supported on the wings. lt will be noted that the wings 15are so proportioned that when they are brought together with their rearends contacting as shown at Figs. 1 and 2 they form a Vfshaped bodyunder the frame.` To maintainthe wingsin such relation flexible members'as the chains 17 are employed secured to the wings in'any approvedmanner as by employing a strengthening rib 1S and eyeybolts 19 with thechains passing over a roller 20 at the front of the frame and rearwardlyto a winding drum 21 mounted on the rear of the frame. The winding'drumis provided at one end with a` ratchet 22 as shown particularly at Fig.3 with a detent 23 which is carried byv a lever 24 standing adjacent aseat 25 upon which the driver is supposed to ride. y y

Vith the device assembled as shown at Figs. 1 and 2 it is driven acrossthe ice or other surface to be. cleaned until the wings 15 areloadedqwith snow or othermaterialy and is then driven off to somelocation where the load may be dumped without detriment.

Arrived at such location lthe lever`24 ,is liftedwhich releases thewinding drum 21 and permits the wings 15 vvto swing out' wardly to`parallel position as shown at Fig.

3, such' .swinging being facilitated by the load andthe position is suchthat the wings are then vmoved with the frame leaving the loadwhere itisdumped and also serving as runners for the device while being returnedto position for another load. `When arrived at the position where thecleaning is to be continued the wings are returned to the position shownaty Fig. l, the chain wound about the winding drum and retained by thedetent Q3 when the device is again ready to perform its operation asabove described.

I claim:

In a scraper, the combination with a framework comprising a straightcross beam and acurved beam rear of and connected at its ends with saidstraight beam, the lower edges of the beams standing in a singlohorizontal plane, means for applying draft to said framework, andaroller and; winding drum mounted on such framework; 1 0f pntlesdepending rigidly from oppositeE .ends of the framework, two wingsstand` ing on edge beneath the framework, ,ai`

-a chain connected with the rear end of the wing and passing over saidroller to the winding drum.

In testimony whereof afX my signature .in presence of witnesses.
